Abstract
A package to encapsulate an optical component includes a RF interface to receive high frequency signals from an external source. The RF interface pins that can be configured as one or more single-ended transmission lines or as one or more differential transmission lines. For example, the RF interface includes four pins that can be coupled in one of two configurations to provide a single-ended transmission line and in a third configuration to provide a differential transmission line. In one embodiment, the first, second, and fourth pins are coupled to ground while the second pin is coupled to receive a RF signal. Alternatively, the first, second and fourth pins are coupled to ground and the third pin is coupled to receive a RF signal. For a differential transmission line, the first and fourth pins are coupled to ground while the second and third pins are coupled to receive a differential RF signal.
